Autofocus speed comparison of mirrorless?

You're exactly right, until Olympus/Panasonic release a camera with a larger PDAF sensor, you will still get occasions where the camera hunts for focus. In most situations I don't really see the issue with CDAF unless I'm trying to shoot a fast moving object, or a non-contrasty area such as a landscape where I want to focus towards a blue sky. In the later case I just switch over to manual focus because it doesn't really matter.

I'm hoping the next Olympus OMD or G/GX series from Panasonic addresses this issue as enough of us have raised it as being problematic. For example I haven't been able to shoot things like birds in flight, or fast moving cars without getting motion blur, or an out of focus shots as a result.
